BACKGROUND OF THE INVENTION

The present invention is directed to photovoltaic systems andmanufacturing processes and apparatus thereof. In particular, thepresent invention provides an apparatus and method for a high-densitysolar module.

As the population of the world has increased, industrial expansion hasled to a corresponding increased consumption of energy. Energy oftencomes from fossil fuels, including coal and oil, hydroelectric plants,nuclear sources, and others. As merely an example, the InternationalEnergy Agency projects further increases in oil consumption, withdeveloping nations such as China and India accounting for most of theincrease. Almost every element of our daily lives depends, in part, onoil, which is becoming increasingly scarce. As time further progresses,an era of “cheap” and plentiful oil is coming to an end. Accordingly,other and alternative sources of energy have been developed.

In addition to oil, we have also relied upon other very useful sourcesof energy such as hydroelectric, nuclear, and the like to provide ourelectricity needs. As an example, most of our conventional electricityrequirements for home and business use comes from turbines run on coalor other forms of fossil fuel, nuclear power generation plants, andhydroelectric plants, as well as other forms of renewable energy. Oftentimes, home and business use of electrical power has been stable andwidespread.

Most importantly, much if not all of the useful energy found on theEarth comes from our sun. Generally all common plant life on the Earthachieves life using photosynthesis processes from sunlight. Fossil fuelssuch as oil were also developed from biological materials derived fromenergy associated with the sun. For human beings including “sunworshipers,” sunlight has been essential. For life on the planet Earth,the sun has been our most important energy source and fuel for modernday solar energy.

Solar energy possesses many desirable characteristics; it is renewable,clean, abundant, and often widespread. Certain technologies developedoften capture solar energy, concentrate it, store it, and convert itinto other useful forms of energy.

Solar panels have been developed to convert sunlight into energy. Forexample, solar thermal panels are used to convert electromagneticradiation from the sun into thermal energy for heating homes, runningcertain industrial processes, or driving high-grade turbines to generateelectricity. As another example, solar photovoltaic panels are used toconvert sunlight directly into electricity for a variety ofapplications. Solar panels are generally composed of an array of solarcells, which are interconnected to each other. The cells are oftenarranged in series and/or parallel groups of cells in series.Accordingly, solar panels have great potential to benefit our nation,security, and human users. They can even diversify our energyrequirements and reduce the world's dependence on oil and otherpotentially detrimental sources of energy.

Although solar panels have been used successfully for certainapplications, there are still certain limitations. Solar cells are oftencostly. Depending upon the geographic region, there are often financialsubsidies from governmental entities for purchasing solar panels, whichoften cannot compete with the direct purchase of electricity from publicpower companies. Additionally, the panels are often composed of costlyphotovoltaic silicon bearing wafer materials, which are often difficultto manufacture efficiently on a large scale, and sources can be limited.

Therefore, it is desirable to have novel system and method formanufacturing solar panels.

It is noted that specific embodiments are shown forillustrative purposes, and represent examples. One skilled in the artwould recognize other variations, modifications, and alternatives.

Although orientation is not a part of the invention, it is convenient torecognize that a solar module has a side that faces the sun when themodule is in use, and an opposite side that faces away from the sun.Although, the module can exist in any orientation, it is convenient torefer to an orientation where “upper” or “top” refer to the sun-facingside and “lower” or “bottom” refer to the opposite side.

FIG. 36 is a simplified diagram of a simplified system diagram accordingto an example of the present invention. Further details of the presentinvention can be found throughout the present specification and moreparticularly below.

In an example, the present method and system utilized a ⅕^(th) stripwidth versus ⅓^(rd), ¼^(th) or ⅙^(th) of a cell strip width based uponsome unexpected benefits and/or results, as shown in the table below.

PV Width Comment Width 78   52 39    31.2  26 mm Cell 4.5  3 2.25 1.8  1.5 Isc = 9A Current standard cell Fingers 80-200 80-150 80-120 80-10080 (Microns) Based on standard cell finger Shading  7.0%  5.8%  5.0% 4.5%   4% Finger shading Cell 98.7% 97.4% 96.2% 94.9% 93.6% 2 mmUtiliza- overlap tion Placements 2X 3X 4X 5X 6X Over standard moduleFill  76%  77%  78%  79%  79% Factor

In an example, the present strip has a width that is the size of the cutcell. In an example, current is directly proportional to the size of thestrip. Fingers have to carry current across the whole length of thestrip, while shading is the area of the strip shadowed by the fingers.In an example, cell utilization is the amount of cell area used foroverlapping versus active area. In an example, number of placements ishow many time as strip must be placed compared to a cell. In an example,fill factor is the efficiency of the cell versus is maximum powerproducing potential.

In an example, the purpose of designing a module to get the IVspecifications , as similar as a conventional module (Voc, Vmp, Isc,Imp, Power). In an example, the present method and designs (lowervoltage, and higher current for the tracker application, higher voltageand lower current for the residential module with module powerelectronics.

In an example, the present method and design uses a 31.2 mm strip width,which optimized the size as standard and module, as well as a currentand voltage similar to standard modules. This allowed the presentinvention to take advantage of standard inverters, electronics, andmechanical features.

The claims and drawings are focused on the interior strips. In anexample, each of the strings of strips can be made with the pseudosquare (exterior) strips as well.

In an example, in the table, it is demonstrated that going to smallerstrips provides higher efficiency. The marginal efficiency gains,however, decline as the strip width gets smaller. The difference betweena ⅕th strip from a cell and ⅙th strip from a cell in efficiency is verysmall. Smaller strips do come with other issues that make smaller stripsless attractive. In an example, smaller strips require more since thereare more of them. In particular, more strips are handled, and assembled.The manufacturing costs and equipment capex increase more than theefficiency gain is worth. In addition, smaller strips lead to more cellto cell overlap that uses up silicon. Having more cell to cell overlapsincreases the silicon cell usage and increased costs.

Most importantly, there are standard module sizes in solar industry thatare primarily dictated by the size of the photovoltaic cell. In anexample, sixty (60) cell modules are primarily used on roof-topapplications. Such sixty cell modules are typically about 1.6 m long by1 m wide in dimensions. Ground mount utility modules are typically 72cells and are almost 2 m long by 1 m wide in dimensions. For the presentmodule, it is desirable to maintain them within one of these formfactors. Almost every installer in the world has racking and mountinghardware designed around this basic size. Many have automatedengineering software for system design that also has these sizesembedded in them. Of course, there can be slight variations, althoughmaking the present module in the standard cell format is highly desired.

Still another feature relates to a open circuit voltage on a cold clearsunny day. Typically, solar module systems are rated for 600 VDC or 1000VDC. The system engineering, inverter designs, national electric codeare all standardized not to exceed one of these voltages. Theinstallation cost is highly influenced by the number of modules that canbe hooked up in series without exceeding the maximum voltage. As such,the present module electrical specification needs to be as similar aspossible to the industry standard modules (60 or 72) cell.

It has been discovered that ⅕th strip width is the best strip width tosimultaneously allow for the maximized performance, lowest manufacturingcosts, industry standard size, and industry standard electricalcharacteristics, each of which has been unexpected. The present ⅕stripwidth is slightly larger in width than the conventional ⅙th stripwidths. The ⅕strip width has higher assembly costs than the ⅙stripwidth. Cell utilization will be less, however, the ⅕strip widthperformance will be about the same. The ⅙strip width module has a modulevoltage that is about 20% higher causing higher installation costs. Inother examples, the ¼cut strips will lose much of the efficiency gainassociated with the ⅕th strip width and will be a much higher currentand lower voltage module than is normal in the industry. There will beincreased costs for handling the higher current including thickerconductors, larger bypass diodes, and maybe a special junction box. The⅕^(th) strip width is novel and benefits unexpected. Generally allconventional modules use ⅙th strip width. It would be great if we couldlock up ⅕th strip width. Of course, there can be other variations,modifications, and alternatives.

This application is also related to U.S. Ser. No. 14/869,130 filed Sep.29,2015 (under Attorney Docket No. A906RO-018110US), titled SOLAR MODULEWITH DIODE DEVICE FOR SHADING, in the name of Kevin R. Gibson, which ishereby incorporated by reference in its entirety for all purposes.
